Summary
Уявимо, що було б, якби Ірума продали Кальєго, а не до лорда Саллівана через своїх родичів, що захотіли собі спадщину і заразом позбутися "білої ворони" сім'ї. Але ніхто не знав, що в гонитві за грошима вони з'єднають справжню сім'ю

Summary
Before the end of the term, Kalego assigns one last task. This task consists of writing a short story from personal experiences whether big or small. He honestly thought he was going to get some cringy stories from the kids about how their parents used to sing them songs or take them out to the amusement park when they were younger. He also believed most of them would be made up. Yet one submission made him question the sanity of one of his students….

Summary
"[...] Kalego slowly shook his head and answered, opening his eyes slightly. "My back..." he replied through gritted teeth. Balam straightened his back completely. "Did I hurt you down there? Where? I need to put a healing potion on you right now!" the gargoyle exclaimed, gently grabbing his buttocks. Kalego shook his head again, faster than before, and replied in a pained voice, "No, not my ass...! M-My back! My back is killing me!" Balam remained wide-eyed for a few moments, unblinking. "Oh..." he muttered, surprised"
Basically Kalego gets a back pain while being intimate with Balam but he doesn't give up.

Summary
Due to an incident in Japan, Iruma had been forced to spend a majority of his life in the area around an odd city known as Danville.
It was.... well honestly he actually found himself enjoying the people there far more than his own parents.
He even made friends with some nice kids over the summer, and found mentorship in a nice evil scientist and his platypus nemesis.
But all good things had to come to an end, and his parents sold his soul for money.
To bad for everyone you can take a boy out of Danville but you can't take the Danville out of the boy.

“I’m pregnant.”
The words were like a spear through the chest. “What?”
“I’m carrying a demon child.”

“And yet, it is.”
Or: Iruma’s mom summoned Kalego as her familiar first and Iruma is Kalego’s son—a half-human, half-demon cambion. 15 years later and Kalego never thought he’d get the chance to meet him until a certain blue haired boy gave a speech at the Babyls opening ceremony.
